Description

Technical Field

[0001] This utility model relates to the field of mining machinery and equipment technology, specifically a mining unloading trolley with screening function. Background Technology

[0002] In mining operations, unloading trolleys are crucial transportation equipment. Traditionally, these trolleys are mostly belt conveyor unloading trolleys, whose main function is to interrupt the conveyor belt and connect the unloading port, allowing for flexible adjustment of the ore stockpile position according to the actual conditions of the mine site. However, existing unloading trolleys have a significant drawback: they cannot simultaneously screen and classify the ore during unloading, resulting in a mixture of coarse and fine ores. This necessitates further screening for subsequent use, consuming considerable time and effort and hindering the fine screening of the ore. Utility Model Content

[0003] The purpose of this utility model is to provide a mining unloading trolley with screening function to solve the problems mentioned in the background art.

[0004] The technical solution of this utility model is: a mining unloading trolley with screening function, including a movable frame, a support frame installed on the movable frame, a conveyor belt installed on the support frame, a screening component that can move laterally arranged below the discharge end of the conveyor belt, a reciprocating push component being drivenly connected to the screening component, a conveyor belt for conveying small particles of mineral material arranged below the screening component and the conveyor belt, and a discharge plate for discharging coarse particles of mineral material arranged below the discharge end of the screening component.

[0005] The aforementioned components achieve the following effects: the movable frame provides a supporting foundation for the overall structure, the support frame is fixed on the movable frame to form a stable installation framework, the conveyor belt on the support frame achieves initial conveying of the ore, and when the ore falls from the discharge end of the conveyor belt, it falls into the horizontally movable screening component. The reciprocating push component drives the screening component to move horizontally back and forth, allowing the ore to shake fully within the screening component. Small particles of ore pass through the screening component and fall onto the conveyor belt below to be transported to the designated position, while large particles of ore slide from the discharge end of the screening component onto the discharge plate for discharge. Through the cooperation of various components, synchronous screening of the ore is achieved during the unloading process, eliminating the need for subsequent screening, improving ore processing efficiency, optimizing the ore processing flow, and increasing the versatility of the equipment.

[0006] Preferably, the screening component includes a screen frame connected to the reciprocating push component, a screen mesh is installed inside the screen frame, and a guide port is provided on the side of the screen frame near the feed plate.

[0007] The aforementioned components achieve the following effects: the screen frame provides space for screening, and the screen mesh, as the core component of screening, separates small and large particles of ore. When the screening assembly moves under the action of the reciprocating pusher, the ore is agitated within the screen frame as the screen mesh moves. Small particles fall through the mesh openings, while large particles move towards the feed inlet and are discharged through the feed inlet. Through the coordination between the screen frame, screen mesh, and feed inlet, the screening and discharge paths are clearly defined, ensuring the orderly progress of the screening process, achieving effective separation of the ore, and improving the accuracy and reliability of screening.

[0008] Preferably, the reciprocating push assembly includes two guide rods fixed on the same side of the screen frame. A side block connected to the support frame is sleeved on the guide rod. A spring sleeved on the guide rod is provided between the side block and the screen frame. A rack is fixed at the end of the screen frame away from the guide rod. The rack meshes with a half gear, and the half gear is connected to a drive motor.

[0009] The aforementioned components achieve the following effects: the drive motor rotates the half-gear; when the half-gear meshes with the rack, it pushes the rack to move, which in turn moves the screen frame. At this time, the guide rod slides within the side block, and the spring is compressed. When the half-gear disengages from the rack, the spring force pushes the screen frame back to its original position, and the guide rod slides in the opposite direction with the screen frame. Through the cooperation of the drive motor, half-gear, rack, guide rod, side block, and spring, the rotational motion of the motor is converted into the lateral reciprocating motion of the screen frame, enabling the screen to continuously screen the ore, enhancing the screening effect, preventing the ore from accumulating on the screen, achieving the goal of high-efficiency screening, and improving screening efficiency.

[0010] Preferably, the top of the support frame has two side plates located on the outside of the conveyor belt.

[0011] The aforementioned components achieve the following effect: Two side plates are fixed to the top of the support frame and located outside the conveyor belt. During the conveyor belt's transport of ore, the side plates prevent ore from falling from either side of the belt. Through the cooperation of the side plates and the conveyor belt, ore spillage during transport is prevented, ore waste is reduced, and all ore is ensured to enter the screening components for screening. This achieves effective collection and transport of ore, improving ore utilization.

[0012] This utility model provides an improved unloading trolley with screening function for mining, which has the following improvements and advantages compared with the prior art:

[0013] Firstly, this utility model's conveyor belt enables the initial conveying of mineral materials on a support frame. The conveyor belt can perform primary screening of the mineral materials, guiding the powder onto the lower conveyor belt. When the mineral materials fall from the discharge end of the conveyor belt, they fall into the horizontally movable screening component. The reciprocating push component drives the screening component to move horizontally back and forth, allowing the mineral materials to shake fully within the screening component. Small particles of mineral materials fall through the screening component onto the lower conveyor belt and are transported to the designated position, while large particles of mineral materials slide from the discharge end of the screening component onto the discharge plate for discharge. This achieves simultaneous screening of the mineral materials during the unloading process, eliminating the need for subsequent screening and improving the efficiency of mineral material processing.

[0014] Secondly, this utility model, through the movement of the screening component under the action of the reciprocating pushing component, causes the ore to tumble within the screen frame as the screen mesh moves. Small ore particles fall through the mesh openings of the screen, while large ore particles move towards the feed inlet and are discharged from the feed inlet under the action of the screen frame. This clarifies the screening and discharge paths, ensures the orderly progress of the screening process, achieves effective separation of ore, and improves the accuracy and reliability of screening.

[0021] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0022] This utility model provides an improved unloading trolley with screening function for mining. The technical solution of this utility model is as follows:

[0023] In embodiments of this utility model, such as Figures 1-3 As shown, a mining unloading trolley with screening function includes a movable frame 1, a support frame 7 mounted on the movable frame 1, and a conveyor belt 2 mounted on the support frame 7. The movable frame 1 provides a supporting foundation for the overall structure, and the support frame 7 is fixed to the movable frame 1 to form a stable installation frame. The conveyor belt 2 performs preliminary conveying of the ore on the support frame 7, wherein the conveyor belt 2 can perform primary screening of the ore, guiding the powder into the lower conveyor belt 3. Two side plates 6 are fixed at the top of the support frame 7, located on the outer side of the conveyor belt 2. At the top of the support frame 7 and located outside the conveyor belt 2, the side plate 6 prevents the ore from falling from both sides of the conveyor belt 2 during the conveying process. Below the discharge end of the conveyor belt 2, a laterally movable screening component 4 is provided. The screening component 4 includes a screen frame 41 connected to the reciprocating push component 8. A screen mesh 43 is installed inside the screen frame 41. A guide port 42 is provided on the side of the screen frame 41 near the discharge plate 5. The screen frame 41 provides space for screening. The screen mesh 43, as the core component of screening, can separate small and large ore particles. Separation occurs when the screening component 4 moves under the action of the reciprocating push component 8. The ore material inside the screen frame 41 is agitated by the movement of the screen mesh 43. Small particles fall through the mesh of the screen mesh 43, while large particles move towards the feed inlet 42 and are discharged from it under the action of the screen frame 41. The screening component 4 is connected to the reciprocating push component 8, which includes two guide rods 83 fixed on the same side of the screen frame 41. Side blocks 81 connected to the support frame 7 are sleeved on the guide rods 83. A sleeve is provided between the side blocks 81 and the screen frame 41. A spring 82 is installed on the guide rod 83. A rack 84 is fixed to the end of the screen frame 41 away from the guide rod 83. The rack 84 meshes with a half gear, which is connected to a drive motor 85. The drive motor 85 drives the half gear to rotate. When the half gear meshes with the rack 84, it pushes the rack 84 to move, thereby driving the screen frame 41 to move. At this time, the guide rod 83 slides in the side block 81, and the spring 82 is compressed. When the half gear disengages from the rack 84, the elastic force of the spring 82 pushes the screen frame 41 to return to its original position, and the guide rod 83 slides in the opposite direction with the screen frame 41.

[0024] Below the screening component 4 and the conveyor belt 2, there is a conveyor belt 3 for conveying small particles of mineral material. Below the discharge end of the screening component 4, there is a discharge plate 5 for discharging coarse particles of mineral material. When the mineral material falls from the discharge end of the conveyor belt 2, it falls into the screening component 4, which can move laterally. The reciprocating push component 8 drives the screening component 4 to move laterally back and forth, so that the mineral material shakes fully inside the screening component 4. Small particles of mineral material fall through the screening component 4 onto the conveyor belt 3 below and are transported to the designated position. Large particles of mineral material slide from the discharge end of the screening component 4 onto the discharge plate 5 for discharge. This achieves the purpose of synchronous screening of mineral material during the unloading process, without the need for subsequent screening.

[0025] The working principle of the unloading trolley with screening function for mining provided by this utility model is as follows: The movable frame 1 provides a supporting foundation for the overall structure, and the support frame 7 is fixed on the movable frame 1 to form a stable installation frame. The conveyor belt 2 realizes the initial conveying of the ore on the support frame 7. When the ore falls from the discharge end of the conveyor belt 2, it falls into the screening component 4, which can move laterally. The drive motor 85 drives the half gear to rotate. When the half gear meshes with the rack 84, it pushes the rack 84 to move, thereby driving the screen frame 41 to move. At this time, the guide rod 83 slides in the side block 81. When the spring 82 is compressed, and the half gear disengages from the rack 84, the elastic force of the spring 82 pushes the screen frame 41 to reset. The guide rod 83 slides in the opposite direction with the screen frame 41, converting the rotational motion of the motor into the lateral reciprocating motion of the screen frame 41. This allows the screen 43 to continuously screen the ore, making the ore shake fully within the screening assembly 4. Small particles of ore fall through the screening assembly 4 onto the conveyor belt 3 below and are transported to the designated position, while large particles of ore slide from the discharge end of the screening assembly 4 onto the discharge plate 5 for discharge, thus achieving the purpose of synchronous screening of the ore during the unloading process.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
